| seroprevalence of toxoplasma gondii in american free-ranging or captive pumas (felis concolor) and bobcats (lynx rufus). | toxoplasma gondii is a major zoonotic agent infecting a wide range of mammals, including wild felids. like domestic cats, wild felids are involved in the complete infective cycle of t. gondii, as they can host in their gastrointestinal tract sexually mature parasites and shed infective oocysts in their feces. in order to evaluate the importance of this wildlife reservoir, 438 serum samples collected between 1984 and 1999 from 438 pumas (felis concolor) and from 58 bobcats (lynx rufus) from north ... | 2004 | 15019138 |
| habitat barriers limit gene flow and illuminate historical events in a wide-ranging carnivore, the american puma. | we examined the effects of habitat discontinuities on gene flow among puma (puma concolor) populations across the southwestern usa. using 16 microsatellite loci, we genotyped 540 pumas sampled throughout the states of utah, colorado, arizona, and new mexico, where a high degree of habitat heterogeneity provides for a wide range of connective habitat configurations between subpopulations. we investigated genetic structuring using complementary individual- and population-based analyses, the latter ... | 2005 | 15910319 |
